IN light of the catastrophic knock-on effects from stepped-up Islamic jihad within America, Israel, and the west at large, our upcoming book release (in August or early Sept. 2016) can’t come soon enough!

IF anything, Orlando’s jihadi massacre (along with countless others) more than demonstrates how deeply intertwined Islam’s soldiers for Allah are with social media, and with FACEBOOK in the forefront. Enabled.

In the hours after he blasted his way into an Orlando gay nightclub, and with his victims lying dead or wounded around him, Omar Mateen took to Facebook to pledge his loyalty to ISIS and threaten more attacks on the civilized world, a key lawmaker privy to the gunman’s posts told FoxNews.com Wednesday.

Mateen, who killed 49 people and wounded 53 inside Pulse early Sunday, died when a SWAT team stormed the club. But in the roughly four hours between his initial rampage and his death, the 29-year-old radicalized Muslim broadcast his twisted message of hate on social media, according to Senate Homeland Security Chairman Ron Johnson, R-Wisc.

“I pledge my alliance to (ISIS leader) abu bakr al Baghdadi..may Allah accept me,” Mateen wrote in one post early Sunday morning. “The real muslims will never accept the filthy ways of the west” …“You kill innocent women and children by doing us airstrikes..now taste the Islamic state vengeance.”

Mateen’s social media accounts were taken down before they could be widely viewed by the public, but Johnson’s committee investigators have uncovered some or all of them. The senator has also written a letter to Facebook executives expressing concern about Mateen’s postings and asking for more information on his activities.

“It is my understanding that Omar Mateen used Facebook before and during the attack to search for and post terrorism-related content,” read Johnson’s letter. “According to information obtained by my staff, five Facebook accounts were apparently associated with Omar Mateen.”

The posts uncovered by Johnson’s committee shed light on Mateen’s actions in the hours that followed his 2 a.m. raid on the nightclub. Mateen, armed with a Sig Sauer MCX assault rifle and a handgun, shot his way past an off-duty cop and sprayed bullets throughout the club, which was packed with more than 300 revelers when he arrived. Some escaped, many died or were wounded and scores more waited out the horrific ordeal, knowing each moment could be their last.

As survivors cowered in darkened rooms, praying and texting police and relatives, Mateen accessed his Facebook account to search for media reports, using search words such as “Pulse Orlando” and “Shooting.” An FBI source told FoxNews.com he also made 16 phone calls from inside the club after the bloody spree began. Investigators are tracking down each of the recipients of those calls.

Mateen proclaimed his hatred for Westerners in one Facebook post uncovered by Johnson’s committee.
